Press Release

Montreal, Québec, June 10, 2024 – Osisko Development Corp. (NYSE: ODV, TSXV: ODV) (“Osisko Development” or the “Company”) announces it has entered into an amending agreement to the credit agreement (the “Amendment”) with National Bank of Canada (the “Lender”) made as of March 1, 2024 providing for a US$50 million delayed draw term loan (the “Credit Facility”), through its wholly-owned subsidiary, Barkerville Gold Mines Ltd.
